EUVD-2025-27022

Comprehensive Technical Analysis of EUVD-2025-27022

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-27022 affects PTZOptics and other ValueHD-based pan-tilt-zoom (PTZ) cameras. These devices use hard-coded, default administrative credentials that cannot be changed by the user. Additionally, SSH or telnet services are enabled on all interfaces and cannot be disabled by the user.

Severity Evaluation: The vulnerability has a CVSS base score of 9.8, which is considered critical. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, which can be exploited remotely with low complexity and without requiring any user interaction.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Remote Access: Attackers can exploit the vulnerability over the network without needing physical access to the devices.
2. Default Credentials: The use of hard-coded, default administrative credentials makes it easy for attackers to gain unauthorized access.
3. SSH/Telnet Services: The enabled SSH or telnet services provide a direct path for attackers to execute commands and gain control over the devices.

Exploitation Methods:

1. Credential Stuffing: Attackers can use the known default credentials to log in to the devices.
2. Command Injection: Once logged in, attackers can execute arbitrary commands via SSH or telnet to manipulate the device, exfiltrate data, or disrupt services.
3. Lateral Movement: Compromised cameras can be used as a pivot point to attack other devices within the same network.

3. Affected Systems and Software Versions

The vulnerability affects a wide range of PTZOptics and ValueHD-based PTZ cameras, including but not limited to:

• PT30X-4K-xx-G3
• PT12X-SDI/NDI-xx (versions <6.3.70)
• PT20X-USB-xx
• 12x Fixed Camera/NDI Fixed Camera (versions <7.2.85)
• PT-STUDIOPRO
• Pan-Tilt-Zoom Cameras (all versions)

A complete list of affected products and versions is provided in the ENISA ID Product section of the entry.

4. Recommended Mitigation Strategies

Immediate Actions:

1. Network Segmentation: Isolate affected cameras on a separate network segment to limit potential lateral movement.
2. Firewall Rules: Implement strict firewall rules to block unauthorized access to SSH and telnet ports.
3. Monitoring: Enable continuous monitoring and logging of network traffic to detect any suspicious activities.

Long-Term Solutions:

1. Firmware Updates: Contact the vendor for firmware updates that address the vulnerability.
2. Credential Management: If possible, update the firmware to allow changing default credentials.
3. Service Disabling: Ensure that future firmware updates allow disabling unnecessary services like SSH and telnet.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations and individuals using the affected cameras, particularly in critical infrastructure sectors such as healthcare, education, and public safety. The widespread use of these cameras in surveillance and monitoring systems means that a successful exploit could lead to:

• Data Breaches: Unauthorized access to sensitive video feeds.
• Service Disruption: Interruption of critical monitoring services.
• Reputation Damage: Loss of trust in the security of surveillance systems.

6. Technical Details for Security Professionals

Detection:

• Network Scanning: Use network scanning tools to identify devices with open SSH or telnet ports.
• Log Analysis: Review logs for unusual login attempts or command executions.

Response:

• Incident Response Plan: Develop and implement an incident response plan tailored to this vulnerability.
• Patch Management: Ensure a robust patch management process to apply updates as soon as they are available.

Prevention:

• Security Policies: Enforce strict security policies for device management and access control.
• Regular Audits: Conduct regular security audits to identify and mitigate vulnerabilities.
